1354 6640 d 5 h palkovsky /kernel/trunk/ Support for mips kbd driver.  
1332 6641 d 23 h palkovsky /kernel/trunk/ Added support for more processes in mips.  
1293 6651 d 5 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6651 d 8 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1278 6654 d 2 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1260 6656 d 22 h palkovsky /kernel/trunk/ Small fixes.  
1258 6656 d 22 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.		  
1227 6663 d 4 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.		  
1223 6663 d 7 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1222 6663 d 20 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1221 6663 d 21 h decky /kernel/trunk/ printf-related and other code cleanup  
1212 6664 d 2 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1196 6670 d 7 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6672 d 11 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1187 6673 d 2 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.		  
1135 6691 d 21 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader		  
1126 6693 d 8 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad order of EPC & STATUS change in syscall_shortcut.  
1122 6693 d 19 h palkovsky /kernel/trunk/arch/mips32/ Set up T9 to entry point on entry to userspace to facilitate better
PIC running.		  
1121 6693 d 23 h jermar /kernel/trunk/ Small textual changes.  
1119 6693 d 23 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.		  
1112 6694 d 9 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).		  
1102 6695 d 21 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6696 d 23 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.		  
1097 6697 d 6 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6697 d 6 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall		  
1094 6697 d 9 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6700 d 2 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6700 d 18 h jermar /kernel/trunk/ Support for user space threads.  
1044 6701 d 7 h jermar /kernel/trunk/ Page table locking.  
1037 6701 d 8 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
983 6703 d 4 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
959 6703 d 23 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6704 d 0 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
955 6704 d 0 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6705 d 1 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
924 6705 d 11 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
906 6714 d 20 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared		  
897 6717 d 20 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
853 6727 d 4 h palkovsky /kernel/trunk/arch/mips32/ Some arc bios tweaks. Wanted to print configuration data, but
the ARC seems to return strange values.
Newport graphics card does not seem to be easy to port, give up now.		  
852 6727 d 5 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)
